Factors to Consider When Installing Custom Windows

There are many factors to take into consideration when it comes to deciding what type of custom windows you need. You need to consider style of the frame and glass, energy efficiency and building codes. You might also incur additional expenses if you need to have your windows custom-sized. You should always review your options and do a cost-comparison before making a final decision.


The first thing you need to take into consideration is the size of the window. If the size of the opening is irregular you must decide if you want to make the hole bigger or smaller to fit a standard size window. This option works best if you are opting for a smaller window, but you will incur the expense of filing, trimming and patching. If you decided on a larger window you may incur costs from adjusting the load-bearings in the wall. It’s always a good idea to get a professional opinion before making a final decision.

Other than sizing, reasons to switch to custom windows include the design and style of your home as well as cost efficiency. You can opt for signature window styles such a bay, oriel or bay windows. Custom styles let you determine the features, requirements and measurement terms of the windows you choose.

You should always research various windows companies before you place your order. One company may consider a certain size standard while another may not, so thus pricing could vary greatly. You might want to opt for smaller standard windows instead of one large custom window as this can help save you money in the long run.


Always be sure to have your custom windows made with the performance and energy-efficiency features that will suit your region and climate. Custom designed windows are usually comprised of the same material as standard windows: wood, aluminum, vinyl, composite or fiberglass. They also usually include the same options for gases, coating, and light-transmittance and impact resistance.

It is also imperative that you make sure that your custom-made windows come with the same warranty that comes with standard windows. You should also ensure that the performance ratings are the same as those of standard products.

Replacement Windows versus New Windows

Once you have made the decision to install custom windows you will have a few things to consider. If the framing is still in good condition, the entire window might not need to be replaced. In this case, you would just order custom frames, unless they are firmly glued to the window frame, or you wish to install thicker glass. Or you could opt for custom replacement windows as long as they are compatible with the original frame. Obviously, the greatest cost would incur from replacing the entire window, which includes the sash, frame, trim and, of course, the glass.


In general, you will have to pay more for your custom-designed windows. Also, you may have to wait a bit longer for your custom windows to be made. Some companies mass-produce certain styles, while others wait until they have a specific order to begin the manufacturing process. If you are ordering in bulk, you might be able to get a better rate. Keep this in mind when it comes time to replace your windows. You might want to wait and replace them all at the same time t save money in the long run.


Unless you are certain that you know what you are doing, you should have your windows both measured and installed by a professional. You will save a great deal of money in the end as this way the installation will be covered under the warranty. If you try to install them yourself and there are leaks or other issues, you will just incur more problems and expenses in the end. It’s always a good idea to have your custom windows professionally installed.
